It can be seen that, in the capillary bed radiation heat transfer ceiling board of the present invention, have employed the overall ceiling board housing in flat rectangular body shape and define the Guan Bi encapsulating structure to capillary heat exchanger tube, why ceiling board housing design is flat rectangular body shape is mat formation for the ease of modularity furred ceiling. the bottom panel of ceiling board housing is thermoconductive material board, as its radiation heat transfer face, and compared with prior art, the capillary heat pipe frame mode that is sticked on thermoconductive material board there occurs obvious change, namely the position that contacts with capillary heat pipe 102 on thermoconductive material board 101 forms the groove 103 of concave downward and the downside tube wall mating shapes with capillary heat pipe 102, the downside tube wall making capillary heat pipe 102 is absorbed in described groove 103 and fits with the cell wall of groove 103 and contacts, when specifically applying, if the cross section of capillary heat exchanger tube is circular, then can design the cell wall cross section of groove 103 on thermoconductive material board 101 to match in the downside tube wall with capillary heat pipe 102 circular arc of laminating, as shown in Figure 3, since so, just the direct contact heat transfer area between capillary heat pipe and thermoconductive material board it is added significantly to, decrease the consumption of heat/cold in heat transfer process therebetween, enhance the heat transfer efficiency between capillary heat pipe and thermoconductive material board, and capillary heat exchanger tube is absorbed in the degree of depth of groove can reach the 40% ~ 50% of capillary heat exchanger tube outside dimension, so that while being easy to be arranged on thermoconductive material board by the cooperation of capillary heat pipe, the direct contact heat transfer area ensured between capillary heat pipe and thermoconductive material board is increased as much as possible,Certainly, if the cross section of capillary heat exchanger tube is other shape (such as rectangle etc.), then on thermoconductive material board the cell wall cross section of groove adopt accordingly the downside tube wall with capillary heat pipe match laminating shape design, on the other hand, groove on thermoconductive material board can pass through punch forming, the moulding process not only having made thermoconductive material board 101 since so is relatively simple, and the lower surface being in thermoconductive material board after punching press in groove 103 position of thermoconductive material board 101 upper surface formation ditch concave downward has been correspondingly formed downwardly convex rib, as shown in Figure 4, thus adding the heat exchange contact area of thermoconductive material board lower surface, and the heat radiation ray at lower fin bar place present local disperse emission state, thermoconductive material board is made also to have possessed better externally heat transfer effect, simultaneously, the lower fin bar of thermoconductive material board lower surface also contributes to spatial noise is formed the scattering of different directions, reduce the effect of indoor environment sound pollution, by the improvement of above-mentioned two aspect heat-conductive characteristics, the heat exchange efficiency being sufficient so that capillary bed radiation heat transfer ceiling board of the present invention is highly improved.
And in capillary bed radiation heat transfer ceiling board of the present invention, the improvement of its structure and performance is also not only embodied in above-mentioned two aspect. although the downside tube wall that capillary heat pipe is absorbed in trench portions directly contacts with thermoconductive material board, but the pipe wall position place that capillary heat pipe protrudes from trench portions is exposed to the space above thermoconductive material board, can cause upwards scattering and disappearing of capillary heat exchanger tube heat/cold, in addition, due on processing technique, it cannot guarantee that it is absolute seamless applying between groove on capillary heat exchanger tube and thermoconductive material board, the gap not fitted tightly inevitably is there is in subregion, if and these clearance spaces are connected with the upper space of thermoconductive material board and capillary heat exchanger tube, the heat/cold also leading to capillary heat exchanger tube travel downward is scattered and disappeared upward. it is directed to this, as shown in Figures 2 and 3, in capillary bed radiation heat transfer ceiling board of the present invention, protrude from the pipe wall position place of described groove 103 part and thermoconductive material board 101 at capillary heat pipe 102 to be all close to towards interval location place between groove in the one side of hollow chamber and laid reflectance coating 104, pass through reflectance coating, not only define being reflected down the distributed heat/cold of capillary heat exchanger tube, also completely cut off the connection at the interstitial site place between capillary heat exchanger tube and groove and upper space simultaneously, thus reducing upwards scattering and disappearing of capillary heat exchanger tube heat/cold as much as possible, in addition, owing to the encirclement of capillary heat exchanger tube 102 is defined relatively closed encapsulated space by ceiling board housing 100, and also filled up heat preserving and insulating material 105 in the clearance space above reflectance coating 104 and between ceiling board housing top panel, therefore a small amount of heat/cold that capillary heat exchanger tube 102 is upwards conducted by the heat transmission of reflectance coating is also closed in ceiling board housing in the heat preserving and insulating material 105 filled, further reduce upwards scattering and disappearing of heat/cold, moreover, the heat preserving and insulating material 105 filled between top and the ceiling board housing top panel of reflectance coating 104 is except playing heat-blocking action, also concurrently form being pressed down against reflectance coating and capillary heat exchanger tube 102, capillary heat exchanger tube 102 is fitted more closely with the cell wall of groove on thermoconductive material board 103 contact, further ensure transmission of heat by contact performance good between capillary tube heat exchanger tube 102 and thermoconductive material board 101.It can thus be seen that, in capillary bed radiation heat transfer ceiling board of the present invention, reflection that the ceiling board housing of relative closure plays in conjunction with the employing of reflectance coating and the filling of heat preserving and insulating material, heat insulation and be pressed down against effect, the heat/cold that capillary heat exchanger tube outwards conducts is made to be passed down to thermoconductive material board as much as possible, reduce heat exchange energy dissipation, improve heat exchange capacity usage ratio, thus further promoting the heat exchange efficiency of capillary bed radiation heat transfer ceiling board of the present invention.
When specifically applying, in the capillary bed radiation heat transfer ceiling board of the present invention, capillary heat exchanger tube can adopt straight tube, it would however also be possible to employ U-tube. When capillary heat exchanger tube adopts straight tube, as shown in Figure 5, the parallel preferably mutually parallel arrangement of each capillary heat exchanger tube 102 on thermoconductive material board 101 forms a capillary heat exchanger tube and lines up, water supply mozzle 106 and backwater mozzle 107 then lay respectively at the both sides that described capillary heat exchanger tube is lined up, and with each perpendicular setting of capillary heat exchanger tube 102, in Fig. 5, other label implications and Fig. 1 ~ 4 are identical; And capillary heat exchanger tube is according to U-tube, as shown in Figure 1, two straight extensions of capillary heat exchange pipe U-shaped kink both sides are preferably parallel to each other, and each capillary heat exchanger tube on thermoconductive material board is preferably mutually juxtaposed parallel form arrangement one capillary heat exchanger tube of formation according to straight extension and lines up, water supply mozzle and backwater mozzle are positioned at the homonymy that described capillary heat exchanger tube is lined up, and with the perpendicular setting of straight extension of each capillary heat exchanger tube. The laying mode of such capillary heat exchanger tube, water supply mozzle and backwater mozzle, the inner space of ceiling board housing can be utilized as much as possible so that capillary heat exchanger tube is arranged on thermoconductive material board and formed the heat exchange area of coverage that area coverage region bigger, each heat transfer effect is comparatively balanced. Heat transferring medium used in capillary bed radiation heat transfer ceiling board of the present invention can be heat transferring medium conventional in the radiation ceiling plate technique of prior art, for instance can be water, cold-producing medium etc. And the concrete material of capillary heat pipe and thermoconductive material board, the manufacture material of capillary heat pipe and thermoconductive material board in existing radiation ceiling plate can be adopted, and as preferably, when using water as heat transferring medium, capillary heat pipe is preferably with vinyl tube, it is while disclosure satisfy that heat exchange property demand, contributes to reducing cost; And when adopting cold-producing medium as heat transferring medium, capillary heat pipe is preferably with copper pipe, to guarantee that capillary heat pipe has excellent heat conductivility and Corrosion Protection. And the material of thermoconductive material board is preferably with galvanized steel plain sheet so that it is except possessing comparatively excellent heat conductivility and Corrosion Protection, additionally it is possible to take into account aesthetic property simultaneously. In addition, owing to thermoconductive material board is as the bottom panel of ceiling board housing in capillary bed radiation heat transfer ceiling board of the present invention, consider in summer cooling process, likely form condensation at the lower surface of the thermoconductive material board of thermoconductive material board, it is easy to cause condensation to assemble and drop onto the indoor problem affecting health; Therefore, the lower surface of thermoconductive material board can also further lay hydrophilic material or antifogging coating layer; Condensation can be formed absorption by hydrophilic material, make condensation not easily drip and be attracted on hydrophilic material and volatilize, thus the health pollution problem preventing condensation from assembling drippage and causing; But for the weathers such as south China comparatively humid region, the lower surface of thermoconductive material board adopt hydrophilic material be likely to back cause mouldy because its water suction for a long time is moistening, so being more suitable for laying antifogging coating layer on the lower surface of thermoconductive material board in these areas, antifogging coating layer is possible not only to condensation be formed absorption and prevents it from assembling drippage, and antifogging coating layer self can't be condensed and be infiltrated, therefore mouldy without causing, result of use is more preferably.
In addition, it should be noted that, the capillary bed radiation heat transfer ceiling board of the present invention have employed modular design, polylith capillary bed radiation heat transfer ceiling board can be adopted to mat formation on indoor roof, and owing to capillary bed radiation heat transfer ceiling board being provided with the water supply interface for connecting water
